The guide member 37 guides the liquid in the immersion tank 31 to circulate to the ink absorber 35, which absorbs the ink in the liquid in the immersion tank 31.
[0055] After the inkjet tip 131 is soaked, the output end of the lifting member 32 retracts, causing the nozzle body 13 to return to its original position. The moving member 43 drives the dredging box 41 downward, allowing the ink inlet tube 132 to pass through the opposite passage hole 411 and support the sealing plate 472, thereby connecting the ink inlet tube 132 with the interior of the dredging box 41.
[0056] The water supply pump 45 transports the liquid inside the water tank 44 to the inside of the unclogging box 41, and the air supply pump 46 applies pressure to the liquid inside the water tank 44, so that the liquid inside the water tank 44 quickly enters the inside of the nozzle body 13 through the ink inlet tube 132, and is sprayed out through the inkjet end 131 to unblock the inkjet end 131.
[0057] After the inkjet end 131 is cleared, the output end of the control moving member 43 retracts and resets. The output end of the moving cylinder 52 drives the moving platform 51 to move below the nozzle body 13. The output end of the supporting cylinder 57 extends, causing the supporting block 56 to propel the cleaning cloth 55 against the inkjet end 131. Then, the output end of the cleaning cylinder 54 retracts and contracts, causing the cleaning platform 53 to drive the cleaning cloth 55 to reciprocate relative to the inkjet end 131, allowing the cleaning cloth 55 to clean the stains on the inkjet end 131.
[0058] After the inkjet end 131 is cleaned, the air inducing member 61 and the heating member 62 are started to deliver hot air flow to the inside of the housing 1 and quickly dry the wet nozzle body 13, thereby achieving automatic and efficient cleaning of the nozzle body 13.
[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
